Objective: Most of the studies on the herb Chuanxiong Rhizoma (CR) have focused on the L-arginine-nitric oxide (NO) pathway, but the nitrate-nitrite-NO (NO
ABSTRACT
OBJECTIVE@#To explore the safety of classic Acupotomy in the treatment of carpal tunnel syndrome.@*METHODS@#Twenty six adult specimens (15 males and 11 females), aged 60 to 95(82.54±6.94) years old, were selected from 10% formalin antiseptic fixation. There were 52 sides(two of them could not be tested). The study period was from November 2017 to May 2018. The specimens were collected from the body donation center of the school of basic medicine, Peking University. The operation of releasing the transverse carpal ligament on the human body specimen was simulated by the classic acupotomy, and the distance from the four points to the surrounding anatomical structure was measured to calculate the direct injury rate to the nerve and blood vessels, and the shortest distance between the acupotomy and the nerve and blood vessels was defined as ≥2 mm as safety.@*RESULTS@#In the experimental operation, the direct injury rate of nerve and blood vessel was 14% and 12% respectively. There was significant difference in the rate of direct nerve injury between the four injection points (0.05). Among the four points, there was a statistically significant difference in the safety of nerves(<0.05), and the safety of point 1 and point 3 of radial injection was higher than that of point 2 and point 4 of ulnar injection(<0.05). There was significant difference in the safety of blood vessels between the four points(<0.05), and the safety of radial point 1 was higher than that of ulnar point 2 and point 4 (<0.05).@*CONCLUSION@#The safety of the classic Acupotomy for carpal tunnel syndrome is related to the location of the needle entry point, and the safety of theradial proximal end of the needle is the highest.

Stenosing tenosynovitis of styloid process of radius(de Quervain's disease) which abductor pollicis longus and extensor pollicis brevis in the first extensor chamber are affected by resistance when sliding, the incidence is affected by anatomical variations. Symptoms, signs and auxiliary examinations can diagnose the disease. Slight dQS can be improved by rest, brace, restriction activities, and oral medications. Chinese medicine and physiotherapy also reduce the disease. Needle knife therapy is a Traditional Chinese medicine minimally invasive surgery, which is also a step-by-step treatment between conservative treatment and open surgery to loosening the compression of the first extensor chamber. Steroid injection is a more common treatment in this disease, and its efficacy is related to the accuracy of the injection and is affected by the severity of the patient's anatomical variation. Identifying the spacing within the first extensor chamber under ultrasound can help patients better choose conservative or surgical treatment. Surgical treatment can more completely change the condition of dQD from anatomical structure, and clinical should pay attention to the choice of surgical procedure to improve the efficacy and reduce the occurrence of surgical complications. This article discusses the pathogenesis, diagnosis and treatment of the disease from the perspective of anatomical structure. It mainly analyzes the therapeutic targets and the clinical application, which aims to provide reference for the diagnosis and treatment of de Quervain disease.

OBJECTIVE@#To investigate the clinical characteristics and mechanism of cervicogenic headache.@*METHODS@#Fifty-seven patients with cervicogenic headache who were treated from May 2013 to December 2017 and had complete imaging data were selected, including 18 males and 39 females with an average age of(43.26±10.39) years old ranging from 20 to 63 years old. The duration of the disease was 4 months to 35 years with a mean of (11.74±9.47) years. The pain situation, iconography and Tinel sign were analyzed.@*RESULTS@#The patients with cervicogenic headache often had bilateral pain. The regions mainly concentrated in the temporal region, with occipital, head or orbit pains. The VAS scores decreased with the duration of the disease. There were many cases of disc herniation(91.30%), vertebral instability(73.91%), atlantoaxial displacement(56.52%), curvature change of cervicogenic vertebra(54.35%). The number of positive Tinel sign points was between 3 and 24 (13.58±5.8) per patient. The number and extent of Tinel sign were significantly different between the affected side and healthy side(<0.05). C₂,₃ facet joints(92.98%), post mastoid(89.47%), occipital concavity(89.47%), C₃,₄ facet joints(84.21%), third occipital nerve(80.70%) were the positive Tinel sign points in patients with cervicogenic headache.@*CONCLUSIONS@#The iconography changes of cervicogenic headache and Tinel sign may contribute to the clinical diagnosis and mechanism of the disease.

Objective To compare the efficacy of hematoma evacuation between transsylvian-transinsular approach and transcortical approach in hypertensive basal ganglia hemorrhage.Methods The patients with hypertensive basal ganglia hemorrhage who underwent hematoma evacuation via transsylviantransinsular approach and transcortical approach were enrolled retrospectively.Demographics and baseline data,as well as the outcome (the modified Rankin scale 0-3 as good outcome and ≥4 as poor outcome) and mortality at 3 months were compared in both groups.Results A total of 68 patients with hypertensive cerebral hemorrhage (40 cases via transsylvian-transinsular approach and 28 via transcortical approach) were enrolled.There were no significant differences in the demographics and baseline data between the two groups (all P＞ 0.05).The good outcome rates in the transsylvian-transinsular approach and transcortical approach at 3 months after surgery were 52.50％ (21/40) and 21.43％ (6/28),respectively.The former is significantly higher than the latter (x2 =6.642; P=0.01); the mortalities in the transsylvian-transinsular approach and transcortical approach were 2.50％ (1/40) and 21.43％ (6/28),respectively.The former is significantly lower than the latter (Fisher's exact test,P=0.017).Conclusions The clinical efficacy of hypertensive basal ganglia hemorrhage via transsylvian-transinsular approach is better than the transcortical approach.
ABSTRACT
<p><b>OBJECTIVE</b>The effects of lentivirus-mediated suppression of Cyclin Y (CCNY) expression on the proliferation of laryngeal cancer cells were investigated in vitro.</p><p><b>METHODS</b>The lentivirus vectors containing a small hairpin RNA (shRNA) to target CCNY were constructed.Hep-2 cells were divided into the following two experimental groups:the negative control group (control lentivirus infected cells) and CCNY knockdown group (CCNY shRNA-expressing lentivirus infected cells). After Hep-2 cells were infected, Real-time PCR was used to measure CCNY expression. The influence of CCNY on the proliferation of laryngeal cancer cells were assessed using MTT and colony formation experiments.Each experiment was performed in triplicate and repeated three times.</p><p><b>RESULTS</b>Lentiviruses expressing shRNA against CCNY were constructed and Hep-2 cells were infected with above mentioned lentivirus at MOI (Multiplicity of infection) of 120.Real-time PCR analysis showed that the mRNA expression of CCNY in Hep-2 cells in the knockdown group was significantly decreased (P < 0.05); the mRNA level of CCNY was 75.3% lower in the si-CCNY group than in the si-CTRL group. After 5 days of lentiviral infection, the cell viability was significantly lower in cells infected with the CCNY-shRNA lentivirus compared to cells infected with the control lentivirus following a 6-day incubation. The colony number was decreased by 60% in Hep-2 cells infected with the CCNY-shRNA-lentivirus infected cells following a 10-day incubation.</p><p><b>CONCLUSIONS</b>The results suggested that lentivirus-mediated downregulation of CCNY expression decreased the proliferation and growth potency of laryngeal cancer cells.Lentiviruses delivering shRNA against CCNY may be a promising tool for laryngeal cancer therapy.</p>
